Which company published the Harry Potter books in the United Kingdom?

Bloomsbury published the Harry Potter books in the United Kingdom.

The London-based publisher acquired the UK rights to Harry Potter and the Philosopher’s Stone, which appeared in 1997. The book became the first in a seven-volume series and helped transform Bloomsbury into a major international publishing name.

Scholastic published the books in the United States, where the first title was retitled Harry Potter and the Sorcerer’s Stone. That title change is a frequent source of confusion, but it does not mean Scholastic was the original UK publisher. The UK edition retained “Philosopher’s Stone.”

Bloomsbury’s publication of the series was a major milestone in modern children’s publishing. The company continued to publish Rowling’s Harry Potter novels in Britain, while international editions were handled by different publishers in different territories.
